Lenses
Microscopes have a two lens system, objective and ocular.
Objective Lens
Ocular Lens (Eyepiece)
The Objective Lens is the lens
closest to the specimen or object.
The Ocular Lenses (Eyepieces)
are the lenses closest to the eye.
Light Bulbs-Caution
1. Turn off the microscope when not in use to preserve the life of the bulb.
2. Never touch a light bulb directl
y, especially when it‟s turned on.
a. The light bulbs can get hot enough to burn skin. Wait until the bulb
has cooled completely before handling it.
b. The oil from your skin will create a hot spot on the bulb which will
damage the glass, dramatically shortening the life of the bulb.
c. When changing light bulbs cover skin with cloth or paper to handle
the bulb. This will protect both you and the bulb.
3.
Hot bulbs will not damage the microscope. AmScope‟s microscopes are
designed specifically to handle the heat ou
